Hello World Application using Aspose.Slides for C++

Overview

This article shows how to create a simple Hello World PowerPoint presentation using Aspose.Slides. The example demonstrates how to create a new presentation, access the first slide, add a rectangle AutoShape at a specified position, insert a text frame containing the Hello World text, and adjust the shape and text formatting.

It also explains how to make the text visible by changing its color to black, hide the shape border by setting the line color to white, remove the shape fill, and save the presentation as a PPTX file.

Steps to Create a Hello World Application

Follow the steps below to create Hello World application by using Aspose.Slides for C++ API:

• Create an instance of Presentation class
• Obtain the reference of the first slide in the presentation which is created on instantiation of Presentation.
• Add an AutoShape with ShapeType as Rectangle at a specified position of the slide.
• Add a TextFrame to the AutoShape containing Hello World as default text
• Change the Text Color to Black as it is white by default and is not visible on the slide with white background
• Change the Line Color of the shape to white in order to hide the shape border
• Remove the default Fill Format of the shape
• Finally, write the presentation to desired file format using the Presentation object

The implementation of above steps is demonstrated below in an example.

    // add an AutoShape of Rectangle type
    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 150.0f, 75.0f, 150.0f, 50.0f);

    // add TextFrame to the Rectangle
    shape->AddTextFrame(u"Hello World");

    // change the text color to Black (which is White by default)
    auto portionFillFormat = shape->get_TextFrame()->get_Paragraphs()->idx_get(0)->get_Portions()->idx_get(0)->get_PortionFormat()->get_FillFormat();
    portionFillFormat->set_FillType(FillType::Solid);
    portionFillFormat->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Black());

    // change the line color of the rectangle to White
    shape->get_ShapeStyle()->get_LineColor()->set_Color(System::Drawing::Color::get_White());

    // remove any fill formatting in the shape
    shape->get_FillFormat()->set_FillType(FillType::NoFill);

    // save the presentation to disk
    pres->Save(u"output.pptx", SaveFormat::Pptx);

    return 0;
